"Poor" battery life on a brand-new S20 FE (Android 12)? - Samsung Galaxy S20 FE Questions & Answers

Hi everyone,
I got my new S20 FE just a few days ago, and I'm still getting used to it, but I wonder if having to charge the battery every day on average is "normal" or not.
When I plug the phone into the charger, the battery is never flat. Rather, it's hovering at around 30%, and I usually stop charging when it reaches 85 to 90%. I use the 15W (?) charger that was in the box, so no ultra-quick charge for this one.
I tried to plug it into a Xiaomi/Poco 33W charger for a few minutes, just to see if it would speed things up, but the remaining charging time was the same as with the regular charger so I reverted to it, just to be on the safe side.
Still, I wonder if it's normal to have to recharge the phone every day, when my Poco X3 Pro needed to be charged every two days on average. Granted, the Poco has a bigger battery, but it has an LCD screen instead of an AMOLED.
I spend a lot of time on Twitter, especially in the evening, mostly, but that's it. No gaming of any kind.
What say you?

Hi,
I've turned Auto brightness off. I'll tell you if it changes anything in terms of battery life. I've also set AOD to fixed brightness instead of auto.
Thanks for the tip!

No problem, thank you for the question!

I think that debloating is not a bad idea, also try to go to all individual apps settings and set the battery to Restricted, except mail and messaging apps, so they won't drain the battery when you're not using them. Lowering the screen refresh rate also helps a bit, as well as restricting mobile data to 4G only, if you don't need 5G. Also, you can limit processor speed, turn Adaptive battery on and Enhanced processing off.

Hi again!
I've changed network settings to 4G and below since my SIM doesn't give me access to 5G yet, but battery life was still iffy. I then changed the network settings to something called "GLOBAL", and it's a bit better, though I don't know what that setting does exactly.

It also depends on how much your using your phone, what apps your running (games vs non-games, etc).
For example, I've played some games, but mainly have been on the internet via apps like social media, email, web browser.
I'm currently at 55% And it's been over 24 hours since I last fully charged it. The Battery graph says based on how I've been using the phone that I still have about 1d 3h left.
I do usually charge once a day, but it's definitely more than 24 hours after the last charge. I went to bed last night with over 62% left after having charged it probably 12 hours prior. When I woke up this morning, it was done to 59% and since then, is now at 55%.
So I've been pretty pleased with the battery life for me. Whether that's good or bad, I have no idea but it's definitely better than my last phone.

I don't do games on my phone (in fact, I don't do games at all, period), but I think the AOD being set on automatic lighting could have something to do with my relatively poor battery life. I'll try to set it to a fixed brightness and see if it changes things, though the brightness scale is pretty rudimentary. Maybe the light sensor is turned off when automatic brightness is off.
I usually spend more time on Twitter when I'm on the phone, so this could explain that.
Another possible factor is my application launcher: I use Microsoft Launcher, which I adore, but every time I wake up the screen, it does a position fix to update the weather widget. That could also explain why my battery drains faster than I expected.
I've just set AOD to fixed brightness. I'll tell you if it helps or not. Thanks for your input anyway!

I used to use Microsoft Launcher, but then switched to Nova launcher. However, since getting this phone, I've moved to OneUI and I'm loving it. I haven't really changed anything. AOD is set to whatever it was out of the box and I've been on Twitter and the web since I last posted and I'm currently at 53%.
I think I have seen MS Launcher be a battery hog if I remember. Nova isn't as bad, but OneUI seems to work great.
Also, the number and type of widgets you have installed could also cause battery drain. For me, I only have one screen. I use smart widgets to "stack" widgets I need which are calendar, weather (from WeatherBug), Brave Search, PowerAmp (for music) and then the phone maintenance widget. So far, battery life is pretty good like I've said.
You can also go into Settings->Battery and Device Care and maybe check in there to see what might be eating up your battery the most.

I like the look and feel of MS Launcher, compared to others (I believe I've tried them all over the years...), even if I have to admit Nova is a close second. MS Launcher is a possible culprit, obviously. I may switch back to One UI to check how things are going, I don't know.
I've just topped-off the battery, and just idling, the phone is supposed to last over 2 days until the next charge, but I know it won't last that long.

So I got my phone used (only 2 months, still has back poly attached) and it came with august 1 update and the battery drain on it is abysmal. I can see the battery go down while I'm browsing insta or whatever, not even gaming. You know what instantly fixed it? Downclocking my gpu and cpu using FKM. But this is not a pretty solution as it requires root and I would like to experience stock without root for a bit.
Which makes me think the system isn't properly downclocking the soc when idle leading to increased drain. I would like to know if anyone has a better fix than just disabling all the options on your phone.

Well, considering it's used (was it refurbished or did you purchase it off eBay or some other market)? That might be why it was being sold. You said 2 months. Does that mean it was only used for 2 months or you've had it for 2 months? If the phone itself is only 2 months old, who knows how the previous owner used the phone.
Did you do a factory reset when you got it to ensure it was back to stock settings? If so, then it might be your battery is bad and could be the reason it was sold/returned by the previous owner. If you haven't factory reset it, that is possibly the only other option that I can think of if you've already rooted and downclocked it.
Mine was new when I got it a few weeks ago and the battery lasts 1.5 days for me, even with the refresh rate set to 120 Hz. And that's with moderate use (playing games a bit, browsing the web, texting, phone calls).
You might want to try setting your screen refresh to 60 Hz to see if that helps as well if you haven't done that yet.
Go to Settings->Display->Motion Smoothness and select "Standard" to set it to 60 Hz refresh. That will save some battery as well.
See if that helps as well. If not, and as I stated, if you haven't done a factory reset, that might be your only other option unless someone else has something I haven't thought of.

Yeah I got it from a store second hand. Came with the back poly still attached and no damages on the body. A killer deal. As for the battery issue, I had flashed wrong region stock rom. After learning what csc meant and figuring out I was on the wrong region I flashed the right rom and now my battery life is top notch. On a side note it has only 54 charge cycles after I got it.

Glad you were able to figure it out. Even though the phone is reaching 2 years since it's release, I've been very happy with it. My S7 finally died over a week ago after 5+ years of dependable service.

This is actually the second device I bought this year. At first I upgraded my Redmi Note 5 Pro which gave me 4 years of great service. Could have reached 5 but then I would not be able to exchange it so I did and got a Redmi Note 11 Pro Plus 5g. Considering how much I paid for it I was more or less satisfied except the camera. Then I bought this after months of careful consideration and also because it was a killer deal. I got a brand new device for half the price. Flagship specs at 33k bdt. You can't get a better deal.

Battery Life.. My dad is complaining constantly.

So my dad was complaining about his battery life, how it only lasts 3 hours. We got him a replacement and he's still complaining. I do not use WP7 phones. I'm more of android and really never explored the WP7 world. Is there any advice you can give?
What he does on the phone,
He calls people often, Spends time on the phone. Email. Low amount of texting, I'm trying to explain to him that for one he has it set to auto brightness which doesnt help and that with the screen size he has doesn't really help the matter in days usage. Also he's always connected to WiFi (not sure if that helps, but with android it does)
I disabled location, Auto Sync, set brightness to medium and he's complain he barely gets 3 hours out of the damn phone. I told him he needs a bigger battery. From what I've seen as far as Battery size at stock for the HD7 it's like 1100, which seems rather low. I told him I'd get him a much bigger battery which would help.
Your thoughts? greatly appreciated. Thanks!

Did you check his email/s sync settings? If he has multiple accounts that sync every 15mins, that can drain battery pretty quickly. If he is on wifi all the time, then disable 3G. Make sure apps don't run in the background. Make sure he closes out every application. And yes, and extended battery will help. And just for a little fun, this hasn't been proven, but having a black wallpaper may improve battery life.
Personally, my HD7S will last 2 days. I have brightness on low, manually sync email accounts. I have wifi on and play music all day. Is he running mango?
My HD7 lasts 2-3 days, depending on use. There is obviously something wrong with your dad's battery, firmware or something.
this happened with me too.
I just turned off "show open wifi networks".
It vastly improved battery life.
I don't remember doing anything else.
Let us know if that solves the issue.

Rogue Apps from the market can cause battery drain.
I had one such and it made the battery die in less then 5 hours.
I did a hard reset just to be sure and then all was well and made sure I did not install that app ( cant remember which one it was , but it was a receipe one)
ALso if you are away from wifi its best to turn it off as otherwise it will keep scanning for wifi all the time hence draining the battery.
Generally the HTC battery is weak mine dosen't last more than 8 hours with normal use
+1 on the advice here
I can get a full day (7am to 11pm) from my HD7 without constantly having to turn on / off Wifi. I would typically have emails set to check every half hour, including weather etc. I make a few calls and send a good number of texts, run a few apps etc. If the battery is under pressure at some point I'll just turn off Wifi. If I'm travelling abroad and I don't want to Roam, I will turn off data naturally but I will also turn off 3G to save extra battery.
If I want to squeeze another hour or two out of the battery when I'm away from a charger I will turn the battery saver on. Automatic brightness should be fine as well; no need to set it to the dimmest setting all day.
The biggest battery killer is if you have your email set to check constantly; set it to 15 or 30 minutes and you will get an amazing improvement in battery life.
I should also mention that my HD7 is just over a year old, so I ordered a new battery for it recently which has definitely helped. New batteries are quite cheap and make a big difference. It's also handy to have the old battery in the bag just in case of emergency.
Pick up an Anker 1350mah replacement battery. I bought one and gained about 15-25% better life depending on usuage. I have 3 push email accounts, FB, Twitter, and Link'din all synced. I get between 5-9 hours of heavy use. 1+ day on the weekend when it's not getting bombarded with work calls and email.
If he can reduce the refresh rate on emails, this will extend the battery greatly. Good luck.
Dies the setting as items arrive under email account drain the battery?

Sorry for hyjacking this thread but I have issues too with the low battery duration of my HD7.
Tried the email advice with no luck, when I put it in before I head to bed and take it out in the morning (around 7am) it doesn't even last till after till after dinner (around 6PM), during which I haven't even done much due to not having time as I'm in class.
But then I read this "hard reset" which I've just done but what is the best thing to do, performing a Hard Reset and
- restoring to the last saved point (which was a few days back due to the 7740 Tethering update)
or
- updating the phone and installing every single app manually again?
Havent found info about this anywhere on the forums, everyone just says "hard reset" but after that there are still 2 options to consider
Thanks.

I did the same, the Anker battery is good. With e-mail updates hourly (not push as I can sync as I need) and medium voice use, I'm getting 36 hours from a charge.

Is battery drain possible due to hardware damage?

So over the course of time I have used many different ROMs and also have had 5 batteries for my Note so far.
All ROMs gave me terrible battery life, except the stock android for around the first year, eventually it started giving me terrible battery life too.
So that got me wondering, is it possible that some kind of faulty hardware on my Note's motherboard is causing those battery drains?

I'm pretty sure that would be possible, but I'd make sure to rule out any other cause you can rule out first.
First thing to do is check on who or what is consuming the battery, so installing something like CPU Spy will let you know if the phone just keeps running at top speeds.
Because there simply isn't enough juice in these batteries to allow all parts of the phone to run full throttle for hours.
Smart phones are really at their best, when their just sitting idle and then they really shouldn't consume any power. That's what you need to check: Does it really slow down and sleep, when you're not actively using it?
And CPU Spy (or similar tools) will give you that info by telling you how much time the CPU has spent at each speed setting. If it doesn't drop to deep sleep when the phone if off the charger, screen switched off at the home screen but stays running at 100-500MHz, then you have found the reason for the miserable battery life. Now you'd just have to find what's causing it.
And that could be a long story journey...
However you could start with an empty ROM fully wiped, nothing but the ROM and the minimum set of GAPPS installed (and CPU Spy or similar for checking) empty internal SDcard, expecially no media files. If you have an external SD card, best remove that initially so you don't have to delete any data you keep on there.
If then the Note isn't guzzling battery and sleeping deeply when not used, your hardware is fine.
Then it's just a matter of adding item after item, always checking of that is causing any change to CPU states and energy consumption.
You should also try to find out of any of your five batteries has issues and use a known good one for the testing.

Okay to begin, the phone never drains battery when idle, never. If I charge to 100% at night around 23:00 , in the morning it would be around 90%. So that seems fair enough. Because I keep my EDGE / 2G activated at all times.
The real problem is when the screen is turned on (doesn't matter what I do).
I tried to keep the screen on for one hour, idle, doing nothing. Battery drained by a whooping 25%. So basically it's my screen which is consuming my battery. I didn't try this when I made this thread, so there's no mention of this in the first post.
So I don't think any other apps are consuming anything. Besides I hardly have any apps installed.
I got the gapps from the following link and installed the 'mini' package.
http://forum.xda-developers.com/par...apps-official-to-date-pa-google-apps-t2943900
Apart from I only have WhatsApp, Notepad, Perfect AppLock, AdAway and Chrome installed. Only a few apps since I did a full wipe yesterday night. Even flashed a stock ROM first and began from scratch.
So I don't really think it's any apps consuming any CPU, only screen is eating a ****load. Could it be the damaged screen?
Holy ****! I just recalled while writing this post, I did get this screen of this phone replace once, like one and half year ago. Could that be it? I did get it replaced from a official Samsung store though.

I'd consider playing with the brightness, just to see of something a little lower is good enough for daily use but I'd say that isn't impossible...
While Samsung liked to hype the fact that OLED would only use power on illuminated pixels, mine are mostly white because reading is what I do most on my Notes.
And then this screen on the Note 1 didn't use particularly less energy than a good LCD backlight screen according to the reviews I remember.
I also remember an article which said that the energy consumption on OLED wasn't linear and that the last 20% of brightness might cost 50% more power (the numbers are most likely bogus but the main point was that brightness/energy consumption wasn't linear).
And yes, there is most likely variation between individual screens on OLED and moreover OLED displays decay with use and over time. I haven't noticed it that much with my Note 1 yet, but my older Samsung Galaxy S I-9000 that I passed on to one of my sons developed a brightness issue: Everything below the first 100 lines or so is significantly darker than the top. I don't know wether that's a consequence of his usage pattern (Whatsapp) or some other reason, but I do know that he typically kept the display at top brightness and also kept it lit far longer than I ever did.
I've always been somewhat disappointed by the endurance of the Note 1 but I haven't really noticed any significant change with the different ROM versions. And since I was also somewhat disappointed by the performance of the device I couldn't resist replacing it with the Note 3 when that came out.
That device was better in pretty much every regard, except screen ratio: I really, really liked the 16:10 of the Note 1 a lot better than the 16:9 of the Note 3.

I see. Thank you for the time you took to write this reply.
I always have my brightness to the lowest possible and yet I am facing battery drains.
Anyways, it seems this problem is beyond repair. I have literally tried every solution possible and nothing seems to have worked. So I guess it's time to move on.
Thank you for your time and information.
It's probably my screen that's consuming the battery. It can easily last up to 20 hours with 2G turned on the entire day. But as soon as I turn the screen on and start doing something, battery drains at like 1% every 60 seconds.
How old is your battery?.. I´d say get a new one if it´s older than 1 year..

Battery drain - at&t note 9

Hi guys,
Have been using my new note 9 after replacing it with my s8+. So far it's a pretty good phone. One of the primary reasons for me to get was the large battery such that it will last m even more longer. But I have been noticing poor performance everyday. At the end of the day, I am bleeding to 10%. The s8+ was given to my wife and I compared her usage vs mine and for same amount of screen time I ended up at 30% and she was at 67%. I have less amount of apps installed than hers and she is heavy user of all social media apps. I have been observing my battery performance and what seems to be draining the most is the Android system, Google play services and Android OS. They claim all together half of my battery life. I noticed that there was an update right after I setup my note 9 initially and not sure if that could have caused it. Is there any way I can reverse it to see if it was the update? I have already tried wiping out the cache and shutting down all background activities on those items and blocked notification on pretty much most of the apps. How is everyone else's experience on the battery? I forgot to capture screen shot but will do it at the end of today.

I'm chiming in because I'm currently using the Note 9 ATT variant. My battery life has been pretty decent, but it's tough because the usage and even my "all day" and your "all day" can differ so much. Are you using 1080 resolution or did you set it to the higher resolution? I'm also running the ATT update you mentioned. But I'm also using wifi calling, not sure if that hurts or helps battery life, I haven't used it on my previous unlocked international HTC devices, so I'm just starting to experiment.
Have you enabled any of the battery optimization?
You can go to settings/device maintenance and click on battery on the bottom. I have it set to off in the "presets" but at the lower part of the page you can see "app power monitor" and see the app's power usage per hour. If you've got some that are higher, you can click on just those apps to check them on the list, and then click "save power" and see if your battery life gets better.
Possibly if you're using always on display you can modify that, if it's not something you really need and have already addressed.
Thanks for your reply. I am not running any battery optimization. I wanted to try default. Yes, I looked at battery usage per app and don't find anything bothering or consuming extra battery. Resolution is set to 1080 and always on display is off. Also. Wifi calling is on at all times. I am not sure if I am expecting too much but after using s8+ for over a year I was expecting much decent battery life with less than half of the apps installed on s8+ and having a bigger battery on this beast. I will need to find out how to lower down those Android system, os and Google play services.
My device is unlocked but on AT&T's network and I'm running my screen at max resolution and close to max brightness. My screen and AOD are always one and two with the O/S running a distant third or fourth sometimes fifth. If Google Play Services is consuming that much battery it is constantly running in the background trying to sync or pull data which it's not getting. Focus on that application and you should be fine, my phone is typically at greater than 50% at the end of the day and I use it all the time.

How do you find which app or service is running in background which is trying to pull or sync data?
Just a note, I had to drop t-mobile to make a point with them for screwing with my account. Houston has good coverage but the network is congested and that is an understatement. My battery life went down on my V20 and my note4 when on ATT's network. Not that the reception was always poor, because it is very poor at my house, but speeds and latency on ATTs LTE were like going back to HSPA. Sometimes it was better to turn off LTE and just put up with the super high latency to get decent speeds on ATT.

Go into settings/apps/Google Play Services/Battery and see what it's been doing. You can restrict the app as well from there I believe, also clear the cache. As I stated I would focus on that app specifically.
My experience was rough when I first got the phone as well. I factory restored with Odin and used ADB to remove all the apps I was not going to use. I then i stalled all my apps and the battery life took a hit again. I'd come home from a 9 hour day of work and be in the 40s. I downloaded betterbatterystats and let it monitor my phone overnight. I found that com.att.iqi was running all the time and constantly causing wake locks. I downloaded package disabler pro and disabled that package. Now when I leave work I am at 75% battery for the past two days. By bed time my phone has been off the charger for 18 hours with about 4 hours screen on time and I'm between 25%-35% which is outstanding. I made a thread with my complaint comparing the battery to my iPhone X and was called a troll because android can do no wrong. In short get betterbatterystats and package disabler pro.
Thanks for this, I was wondering if betterbatterystats would work on my Note 9, but hadn't researched it yet. It's a great app specifically for targeting issues like this, but I've always used it on rooted devices so I didn't recall if it worked on unrooted devices. I'm looking forward to trying it over the next few days and slimming this thing down.

Try Wake lock detector lite. One simple adb command allows you see wakeup locks etc ..

My battery life on the ATT version has been garbage too. I was going to return it, but I missed my 14 day window. Thus far, my S9+ was a better device, but I'm hoping the little bugs get squashed in an upcoming update.
One thing I'm wondering about is Bixby. My battery life seems to be pretty decent with ATT. I don't use Bixby, although I haven't disabled the app, I don't have it set up or signed in.

I actually managed to return mine and got another note 9 thinking that I would try it without doing the first update. Unfortunately that software update thing popped up while I was using the phone and I hit continue by mistake. I am kind of thinking about returning this one and getting the s9 plus if I still have this crappy battery life.

I'm not a battery life hawk,but,there's a few things you can do without crippling your phone (some already mentioned) before throwing in the towel.
1) Go to each app in SETTINGS > APPS > MOBILE DATA & turn off ALLOW BACKGROUND DATA USAGE on apps that have this option & where you're absolutely sure this will not impact something important to your usage.
2) Package Disabler Pro was already mentioned,it's well worth the price of admission. This is where you'll likely see the biggest improvement,surely no one here uses every single feature/app on any phone,force stop & disable what you're not using.
3) Again,I'm not a battery stat ninja,I just use my phone as I see fit,but,others have suggested try using FHD instead of WQHD for screen resolution. I myself use WQHD,but,I'm content with my battery life,however,I'd give it a try if I felt the need.
4) If you have NFC on,turn it off until you need to use it,access to it is quick & easy. I myself do not use NFC,but,even if I did,I can't imagine I'd use it to the point to where I'd leave it on 24/7 for convenience of use.
What's important to your usage is in the eye of the beholder,so,that's the extent of my recommendations for battery recommendations. The few I've mentioned should net some improvement without negatively affecting your routine usage.

Yes. But it seems to stop working once the battery level reaches a certain point. I think it was somewhere below 80% , probably 60% . I installed it last night.

I may drop the developer a line,since the app hasn't been updated in a while.
Perhaps there's been some changes in Android 8 that haven't been addressed.
Regardless,I'm gonna try it out.

I'm trying to ascertain which one to use. Apparently this app shows all wakelocks whereas better battery stats only shows partial wakelocks, from the small amount of research that I've done.
The dev apparently doesn't respond and has abandoned the app, again from research I've done

I am trying a rundown tomorrow with power save. Just CPU and screen brightness. I left resolution and network usage on. I don't think brightness does much. It is supposed to be -10% but I have trained my auto brightness some and I have been having to turn it up. So I think only speed limiter CPU 70% is at play.

2 days absolute max battery life with 'normal' use?

Morning all.
Something that has been slightly bothering me since I got this phone....it has a massive battery, it can be heavily customised with roms, xposed modules, magisk modules and all manner of tweaks. Probably one of the most open and dev-friendly devices I've ever had.
Yet, no matter what I do the only way I have ever been able to get more than 2 days out of a battery is to literally not use the phone.
I have had devices in the past such as Xperia Z3 Compact, S7 Active and others with smaller battery that were easily able to push 3 days with regular use. Hell, the Z3C was able to get up to 5 days with a little bit of trickery turning off radios when not in use etc.
Is the extra diagonal inch of screen realestate really enough to destroy the battery longevity? Typically with normal usage I am seeing 2 days with about 4.5 hours of screen-on time.
I've experimented with just about everything to push this out including no official facebook apps, decreased resolution, medium power-saving mode, kernel tweaks (currently using TGP rom and kernel), auto-sync turned off. Going beyond this I feel like you may as well just use a push-button device.
Any devs care to comment? What is the main factor that eats the battery on the Note 9? Is the exynos processor just not that power-efficient? Am I missing some hidden gem?
I guess the next step would be to transition to an AOSP based rom where the customisation is not constrained by baked-in samsung features but again, this is giving up a lot including proper s-pen functionality.
I recently kitted out an LG V30+ for my wife and it is just insane to me that a phone which only has a 3300mah battery can get the same life as the Note9 or better.
Is there some strategy I have missed or is this really the best we can hope for? Seems like an extremely inefficient use of 4000mah to me.

This is what you get when you use a high performance chip.
If it was like cars.. just because the gas tank is big (battery) doesn't mean that the engine won't consume the fuel faster than a more Efficient engine (cpu) with less power.
Other phones might be able to last 3 days, but they also dont have the performance capabilities. Turn on extreme power saving and see how long the phone lasts ...
I'm using stock unbranded ROM. I also adp uninstalled all the Facebook system apps (devil-ware). With Pie + OneUI + Night mode + Dark UI apps, it's the first time I love stock. I bet your non-stock ROM + TGP is the culprit.
I charge nightly on a wireless charge pad; easy on the battery. In Device Care, I run the default "Optimized" setting. I use it moderately for the first 12 hours of my working day (meetings phone calls), and I often have 85-90% charge left at that point. I then use the phone HEAVILY for the next 4 hours (watching video, reading, etc.), and at that point I am never below 50% (often 60-70) when I put it back on the charge pad, go to sleep, and start the whole thing over again. I have the US version (Snapdragon), darkmode and auto brightness is always on, and I use Automate to toggle my wifi off when not home and back on when home. Other than that, I have gps, bluetooth, and phone data always on. Bluetooth pairs with my watch and car, and gps auto-toggles by the kernel whenever I load maps or whenever my Life360 app updates my location (every few minutes).
That's all fairly normal use with a bit of power-savings thought into it. If you cannot get similar performance without your screen brightness jacked way up and wifi always on (that eats battery as you move around), then maybe you have a power-hungry app. Check your Device Care section of Settings, and start watching your "Usage by apps".
Also, it's better to slow-charge than fast-charge (wears it out more quickly). And you are better off charging nightly than waiting two days until it's very low.

A lot of people don't realize the huge difference that your cellular connection strength makes a difference on your battery.
Try working in a all brick/stone bank building, where 250kb/s is a good 4g download speed... Then see what your battery looks like after a few hours.

YEP!
And same goes for wifi.....
wifi and cell radios can really eat up battery if they are trying to maintain a connection in areas where wifi/phone signal is weak. And app like Tasker or Automate can toggle these on and off, depending on your location, and really save battery.
Well, that probably explains a few things. I moved in to a SOLID brick building recently with double glazing everywhere and multiple solid brick internal walls. First time I've ever battled for cell and wifi signal...that does explain a lot. I guess 2 days is still pretty good. Might end up with one of those 10,000mah Chinafones eventually ;p

Brand New Pixel 5, battery seems awful

I upgraded to a Pixel 5 because my Pixel 2 XL was experiencing hardware issues and was going to die. Among them were battery degradation that was leaving me with maybe 3 hours screen on time from a full battery.
The Pixel 5 so far has been barely better. Additionally I went to bed last night with about 79 percent battery, I woke up around 48 percent. I have no idea what's going on but this is fresh out of the box, I got it Thursday like everyone else in the USA. Is this normal? Can anyone suggest how to figure out what's causing this drain?

You might wanna FDR and start fresh. Sounds like something might be hung up from the setup. All reports about battery have been stellar so far.

I did do the setup where you transfer data from your old device. I guess maybe I need to bite the bullet and do it fresh.
Do you know anything about the... I think the setting is called Always On Display or something like that. The setting where when the phone is locked and the screen is off, it always displays the time and notification icons. I had it on my Pixel 2 and it worked great, it's almost necessary for me at this point. I have it turned on also on the 5, but it seems...finicky? At times it shuts off, especially at night. I used to keep my Pixel2 on my nightstand (just laying flat, not on a stand or anything) and the time would be on all night so I could see it at night if I woke up. With the 5 it seems to shut off in the dark. Additionally periodically during the day it sometimes all of sudden jumps to really high brightness, then back down to dim, sometimes it turns off completely and I have to hit the power button or the fingerprint reader to unlock the phone. Even doing the tap to wake doesn't work. Actually that double tap to wake doesn't seem to work at all regardless.
Any info on any of those issues you know about? I've been searching around and I've found basic references to some stuff with that always on display but no direct threads or anything specific.

Not too sure about AOD, I just went with defaults. But last night, my first with the P5, I unplugged at full charge and 7 + hours later it was at 100%. That's never happened but it was face down and on DND. Nonetheless, check out this thread, download the app, non root needs certain permissions, and let it run for a day or so. It should show you what you need to know.
https://forum.xda-developers.com/showthread.php?t=1179809
Did you make sure to charge the phone to 100% before using it??? These lithium ion batteries need to be charged to the max if you want them to last. My pixel 5 wasn't even fully charged it was somewhere around 65% out of the box. I would leave it charging for a half hour or so once it hits 100% just to be sure.

That's incredible. Next time include all 3 screens please. I could get 12 hours of on screen time all on wifi. Let's see you get that on 5G.
Real world battery is best.
I'm seeing great battery life like many others.
I started using AccuBattery Pro. How accurate is the estimated capacity given by the app? Anyone have any experience?
For me the app is estimating battery capacity to be 4,490mAh which is obviously way above the advertised capacity.
Coming from a worn out pixel 2xl this 5 is fabulous the battery is great. I accidentally left the flashlight on for an hour and it barely drained it. The battery is exceeding my expectations. Screen on time at 5 hours and I'm just at 49% with 10 hours remaining. I'm satisfied for sure
Also on Verizon, but no issues for me. Battery life has been amazing, I didn't charge last night (unintentional) and I was going until this afternoon, with mostly light usage. I've never experienced something like that before.
So in case anyone is interested in this, I actually have a hardware defect that was discovered by a user on reddit.
Link Here
The gist is that the proximity sensor is (i think) detecting that something is up against it all the time. This creates issues with things such as the phone screen not turning on when you pull the phone away from your ear when on a phone call, Issues with tap to wake and lift to wake not working, and Ambient display/always on display (whatever it's called now) constantly changing brightness and/or shutting the display off completely. Literally the phone could be sitting there on the table and all of a sudden the always on display goes to max brightness, then down to dim, then up, then shut off completely. I assume all this craziness is hitting the battery hard.
I am trying (although frustratingly) to get Verizon to exchange it for a new phone. My phone acts exactly like in that thread. There's a proximity sensor app that will detect when something is near it and change color. Mine is solid colored and won't change unless you press on the glass near the sensor. Just in case anyone else has this issue come up, there it is.
I'm at 5 hours of screen on time and 17 hours use. The battery is exceptional and I can dedicate more time to work online because of it.
It sounds like you have ported a troublesome app over from your old phone to be honest. I think a factory reset would fix it.

I just finally got my replacement last night from Verizon. Too early to tell if it fixed my battery issues because I had to set everything up and such. But If you have those issues, I would get a replacement. That's a faulty phone.
